Spent Fuel Assemblies Are Lethally Radioactive during Transportation Age (years) Activity (curies/assembly) Surface Dose Rate (rem/hr) Lethal Exposure (time) 12,500,000234,0007 seconds 5600,00046,80035 seconds 10400,00023, minutes 50100,0008, minutes 10050,0002, minutes Spent fuel activity and surface dose rates are provided in DOE-NRC, Waste Confidence Proceeding, Statement of Position of the U.S. Department of Energy, DOE/NE-007(April 15, 1980) Table II-4, p.II-56. NRC defines lethal dose as the dose of radiation expected to cause death to 50 percent of an exposed population within 30 days, typically 400 to 450 rem (4 to 5 sieverts) received over a very short time.
